Description

A kind of repair and energy consumption shock absorption device of beam-column tenon-mortise joint of wood structure

technical field

The utility model relates to the technical field of wood structure engineering, in particular to a repairing and energy consumption damping device for beam-column tenon-mortise joints of a wood structure.

Background technique

Wood is naturally friendly to the human body and regulates humidity and temperature. With the development of the economy, wood structure furniture has become a major trend, and wood structure buildings are also booming. At present, when mortise and tenon joints are connected, glue coating and nail connection are often used to fix them, and there are problems such as formaldehyde pollution, glue aging, nail damage to the surface of the components, and not enough aesthetics.

In the earthquake-prone areas such as southwest my country and the vast rural areas, there are also a large number of wood structure load-bearing buildings such as wood structure, brick-wood mixed structure, and civil-wood mixed structure. These buildings often do not undergo formal seismic load-bearing design, and their structures have been severely damaged during years of use, posing a great threat to the safety of life and property of the general public, and are in urgent need of repair and reinforcement. At the same time, there are still a large number of ancient wooden buildings in my country. Under the influence of external factors (such as earthquakes, wind loads, foundation settlement, etc.) and the defects of the wood itself, the wooden components have also been damaged after many years of use, and the tenon and mortise joints have become loose. , the gap between the tenon and the mortise becomes larger, the tenon is pulled out and falls off, the tenon is squeezed and deformed, and the mortise is enlarged, which makes the connection method change from the original semi-rigid connection to a movable hinge connection, which greatly weakens the building itself. The rigidity of the building exacerbates the collapse and skewness of the building.

The traditional wooden structure reinforcement methods such as U-shaped iron hoop reinforcement, nail reinforcement and other methods are all reinforced outside the tenon and mortise joints. Although it is simple and practical, it cannot solve the situation that the tenon is squeezed smaller and the mortise is enlarged. Reinforcing the outside of the tenon and mortise joints affects the appearance of the building, which is not in line with the concept of repairing the old as the old.

The Chinese patent with the publication number of CN207959515U discloses a repair and energy consumption damping device for tenon and tenon joints in wooden structures, which is used for tenon and tenon joints connected with wooden columns and wooden beams. The connector is a sleeve fixed on the outer circumference of the tenon, the outer wall of the sleeve has protruding teeth, and the teeth are inclined in the axial direction of the sleeve with one end high and the other low.

Although the above technical solution solves the deficiencies of the prior art to a certain extent, there are still the following defects:

The teeth in the above-mentioned technical solutions are protruded from the outer wall of the sleeve, and when the connector and the tenon are inserted into the socket, the teeth will leave a fixed extension from the open end of the socket to the teeth on the inner wall of the socket. The notch at the position not only destroys the structure of the mortise, but also is difficult to play its due role in limiting the position.
